You've been tricked. That's a piece of rope dipped in tar.

Call me an over-cautious scaredy-cat, but I chose to replace it...

I've got a bucket full of them and not one of them ever broke. Amazing piece of equipment considering the forces that get transferred through it.

It's the bit that attaches the mast foot to the mast base. Another type is called a boge joint and it looks more like an hourglass.

It looks like my finger after squashing it on the weekend hooking up some lifting chains - about the same colour too.

Oh, thanks. I just had a look at my mast base and see how that works now. I'd never really looked closely at it. It just seems to flex, so I guess they wear out over time? I thought they were actual mechanical gimbal joints.

I never would have guessed it looked like that when you described it. No wonder that uni felt dodgy.

Yeah I noticed that lovely clear north tendon at xmas.
I wonder if they break because you guys have them stored in a hot car with the gear i.e. heat effected whereas mine have never broken because they are only ever under a house (concrete bunker virtually) with very little temperature differential.

Vando,

On average, how many kilometres do you get from a Tendon?

God Vando, what are you doing to them? I get 2yrs from a tendon and replace voluntarily.
The gear stays in the car for most of summer so it sees 60deg or so for at least say 30 days a year, so dunno about Sausage's bunker theory

Sail more, break more... The one in the pic was new in October, so four months.

+1

I sail 4 times a week, mine last 2 to 3 years.
Agree with Gestalt, Vando you must suffer from tendonitis !

What I've noticed is that the ones that crack are the less frequently used ones, seems that they go dry and break. Whereas the ones that are on the water all the time seems to last for ages !

The Dodgy QLD water where Vando sails. Has to be. If he spent his time in the pristine surrounds of Pookipa he would not have any problem with tendonitis, the typhoid would kill that.
Back on subject I use the rubber unis as they absorb the shocks on PPB a bit better. Generally get 2 years out of them without a problem, in fact I think I have only ever broken 2 in 30 years of windsurfing.

Touch wood never broken one, never looked like breaking one.
Hot as all feck here in SA and on the back of the ute for weeks on end.
Lost more than worn out, I use chinook tendon that has safety rope built in for the unlikely chance it snaps

Out of interest are the tendons that have broken Chinook or another brand?

Here's a few from my bucket

Good point Greeny never looked at that. If the ropes too short transfers the load back onto the tendon rather than just bending.
I never touch the rope though from new but will check it out.

Posting at midnight p1ssed again Greenie . I think the distortion of the tendon is through continual load compression as there is no tension on the rope even at 90+deg.

Vando, The chinook tendons have fine concentric cirlces from the mould at one end of the tendon and perpendicular holes.

PS - my mum says hi too Greenleader.

Just replaced a couple, with Chinook. Nice tight fit in my Chinook base as expected, but quite loose in the other base (brand unknown). Are there different diameter sizes with different brands?
